PSR J0740+6620: Millisecond Pulsar Parameter Estimation Data and Models

Posterior sample files and data products from the 2021 study 'A NICER View of the Massive Pulsar PSR J0740+6620 Informed by Radio-Timing and XMM-Newton Spectroscopy' by Riley et al. The associated repository includes numeric model files, telescope calibration products, Python model modules using the X-PSI framework, and Jupyter analysis notebooks. The work was submitted to the Astrophysical Journal Letters.

Use Cases

• Bayesian parameter estimation for neutron stars based on the included posterior sample files.
• Calibrating telescope models for X-ray observations based on the provided calibration products.
• Reproducing the analysis from the Riley et al. (2021) study using the included Jupyter notebooks.
• Developing or extending models for pulsar structure using the provided Python modules in the X-PSI framework.

Strengths

• Includes posterior samples from a published astrophysical study on a massive millisecond pulsar.
• Provides associated numeric model files and telescope calibration products for reproducibility.
• Contains executable analysis code in the form of Python modules and Jupyter notebooks.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
